		const bool	graphs,
		const bool	fullGraph,
		const bool	jsonOut,

Member Function Documentation

◆ getPrevType()

const char * graphs::Graph_visitor::getPrevType ( const PrevType & prev_type )

Maps PrevType to string.

Parameters

prev_type PrevType to map

Returns: string representation of prev_type

◆ getType()

const char * graphs::Graph_visitor::getType ( const VertexType & v_type )

Maps VertexType to string.

Parameters

v_type VertexType to map

Returns: string representation of v_type.

◆ process()

void graphs::Graph_visitor::process	(	std::vector< Graph * > &	controlGraphsArray,
		std::vector< Graph * > &	parserGraphsArray )

main function

based on the value of boolean class variables "graphs", "fullGraph", "jsonOut" executes: "graphs" - outputs boost graphs to files "fullGraph" - merges boost graphs into one CFG, and outputs to file "jsonOut" - iterates over boost graphs, and creates json representation of these graphs

Parameters

controlGraphsArray	vector with boost graphs of control blocks
parserGraphsArray	vector with boost graphs of control parsers.

◆ writeGraphToFile()

void graphs::Graph_visitor::writeGraphToFile	(	const Graph &	g,
		const std::string &	name )

Writes boost graph "g" in dot format to file given by "name"

Parameters

g	boost graph
name	file name
